VEHICLE-POLE TIP.

SPECIFICATION forming part of Letters Patent No. 439,640, dated November4, 1890. Application filed $eptember 8, 1890. Serial No. 364,227. (Nomodel.)

To all whom it may concern:

Be it known that I, CONRAD F. ELRICK, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Vehicle-Pole Tips; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon.

Figure 1 of the drawings represents a perspective view of my invention,showing the socket-cap inposition to be connected to the pole-tip; Fig.2, a longitudinal section of the pole-tip and socket-cap in positionready for use; Fig. 3, an end view of the socket-cap, and Fig. 4, acrosssection on line m m of Fig. 2.

The present invention has relation to that class of vehicle-pole tipsprovided with means for retaining thereon a socket-cap, such meansusually consisting of a stud and groove upon the cap and pole-tip,respectively.

The object of the invention is to improve the means heretofore employed,whereby a stronger and more durable device is provided, and which willpresent a much neater appearance, and also guard against dirt or gritworking in between the joint formed by the poletip and cap, whichobjects I attain by the construction substantially as shown in thedrawings, and hereinafter described and claimed.

In the accompanyingdrawin gs, Arepresents the end of a vehicle-pole ofthe usual construction,to which is connected the metal tip B, the samehaving a socket O to receive the end of the pole, which is attachedthereto by rivets or other well-known means. The outer end of the socketO is much larger in diameter than the tip B, so as to present an annularbearing-shoulder a, against which the end of the socket-cap D abuts whenin place, as shown in Fig. 2, thereby forming a tight joint between theshoulder and edge of the cap and preventingsand and grit working inbetween the tip and cap, as well as presenting a neat appearance to theend of the vehicle-pole. The pole-tip B, at a point where it joins theshoulder a, has an annular supporting-flange b, which together with theshoulder form a perfect joint and also admit of the socketcap turning onthe pole-tip. Immediately forward of the flange b is a circumferentialgroove 0, and joining this groove is the groove d, which latter extendsthe entire length of the tip B and has an open end for engagementtherewith of a stud 6 upon the interior of the cap D. It should benoticed that these grooves are on a plane below the circumference of thetip B, so as to present a smooth surface for the interior of the cap D,and a more perfect fitting of the tip and cap is secured.

A further feature of the invention is the extension of the groove 01 ata point from the groove 0 to the extremity of the tip, so that the capwill not turn on the tip after being disengaged with the groove 0, andthereby prevented from turning until the cap is entirely removed.

when connecting the cap D to the tip B, the former is in position shownin Fig. 1,which will admit of the stud e being engaged with the groove dand the cap slid over the tip until the inner end thereof abuts againstthe shoulder a and the stud registers with the groove 0, after which thecap is turned to bring the stud out of register with the groove (1 andin engagement with the groove 0, and when the cap is turned to theposition as shown in Fig. 2 the same will be firmly locked to thepole-tip. In removing the cap D it is turned so as to bring the stud eon line with groove cl, when it may be removed. The groove d, extendingthe entire length of the tip,prevents the cap turning while in the actof removing it.

The cap D is provided with a loop E or any other desirable andwell-known means for attaching thereto the holdback straps or chains orthe crossbar or other portions of a harness or attachments used with avehicle-pole.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. The combination,with the socketcap D, having upon its interior a stude, of the poletip B, having groove 0 and the longitudinal grooved, thesame extending the en tire length of the tip, substantially as and forthe purpose set forth.

2. The combination,with the socket-cap D, 5 having stud e, of the socket0, having shoulder (1 and flange b, and the tip B, having groove 0 andthe groove d, the latter extending the entire length of said tip,substantially as and for the purpose specified.

In testimony that I claim the above I have IO hereunto subscribed myname in the presence of two witnesses.

CONRAD F. ELRICK.
